Application :filed May 4, 1914:. Serial No. 836,119.

T0 all u1/720mv it muy concern Be it known that I', CHARLES L. Parson, dr., a citizen of the United States, and a resident of iittsburgh, in the county of Allegheny and fitate of Pennsylvania, have invented certain new and useful improvements in Secondary Racks1 of which. the foilosving is a speciiication.

My invention relates to secondary racks and'contemplates improved features of construction. which will particularly adapt suchraclcs for support-ing heavy wires or cables at some distance from the supporting pole. ifi/ily invention relates to that class of racks iin which wires, such as the secondary wires of a transformer circuit may be strung in vertical instead of horizontal. alinenient, this allowing the taking off of service wires without il'ieaid of-buck arms or spreader brackets. in prior racks theconstruction is such that the insulators and consequently the wires or cables tied thereto are close to jxle rack supporting pole, the racks being ed against one side of the pole. 1t is desirable in many cases to have the wires or cables at some distance from the pole, and the main purpose of my invention is therefore to produce a rack which will support `wires or cables at some distance from the supporting pole and which is of such strength and which can be rigidly secured to the pole that it will not sag or swing lat-- erally when heavy wires or cables are ap plied thereto. in general, the rack of my construction is of v'shape and adapted to receive at its outer end means for retaining insulators thereon and having its sides adapted to receive a pole between their ends and these ends being adapted to be secured to Opposite faces of the pole.

Another object of my invention is to provide eiiicient means for further strengthening the rack, diagonally extending brace arms lsecured to the rack sides being preferably provided.

The features of the invention can be read l ily understood by reference to the accompanying drawing ip which- Figure 1 is a perspective view of my 11nvproved rack, and Fig. 2 is a top view thereof.

The 'rack is in the form of a jb structure comprising any number of V-shaped jib Aframes 5r secured at their opposite ends to vertical bars 6 and land supporting at their front ends a bolt 8 for receiving between the'franies suitable insulators 9. Each jib frame may be of two pieces but preferably a single length of suitable bar is bent midway to forni at the bend a loop or sleeve section 5 for receiving the bolt 8. Channel bar can advantageously beA used as this gives great strength but is very light. After bending, the limbs of each frame are secured together near the sleeve by a rivet 10 as shown, or spot welding may be resorted to. 'The ends of each frame are secured to the bars 6 and 7 either by rivets 11 and 1l as shown, or they may be secured by welding. The bars G and 'l' receive -between them the support such as -the pole p, and in the bars suitable boit holes 12 and 12 are provided. The bolt 8 is slipped through the successive sieeves 5 and through the insulators and may be held in place bya cottr pin 13, as shown. By securing the ver ical suppo'rting bars Gand 7 to the opposite faces of a pole, the inner ends of the rack sides {irfnly clamp the pole and the rack ,is rigidly secured against lateral swing when @heavy wires are secured to the insulators. Where very heavy wires or cables are supported it may be desirable to brace the structure to prevent sagging thereof and I preferably provide brace bars 14 and 14C for the sides of the rack, these brace barsiextending diagonally. The bar 14 is shown extending from the upper end ofsupporting bar 6 to the front end of the vlower jib frame.

The upper end of the brace bar may, as shown, be secured by the rivet 11 which connects the upper end of supporting bar 6 and the one limbof the upper jib frame, while the-lower end is extended between the limbs of the lower j ib frame and is received by the rivet 10 which holds these limbs together, rivets 15 securing the brace bar to the correspending limbs of the intermediate jib frames. The other brace bar 14: is shown as extending diagonally from the lower end of supporting bar 7 to the outer end of the upper jib frame, the rivet 11 securing the lower end of bar 7 to the lower jib frame serving also to secure the lower end of the brace bar, while the upper end of the brace bar extends between the upper ends of the jib frame and is received by the rivet 10 which secures together the limbs of this jib frame, rivets 16 securing'the brace bar to the corresponding limbs of the intermediate jib frames. These brace bars by being rigtti mit

tai

idly secu-red to the various jib frames locky supporting' bars being necessary, the frame therefore requiring very little space for its support.

rlhe structure shown is very eliicient for Supporting heavy wires and cables at a distance from the supporting pole, the rigid clamping of the pole by the rack sides and the rigid securing of the supporting bars to vthe opposite sides of the pole will prevent any lateral swing of the structure. The diagonal brace bars greatly strengthen the structure Where extra heavy wires or cables are to be supported thereon. Instead of' having the brace bars at angles with each other they could, of course, be parallel but the arrangement shown is more practical and gives the same results as though the braces Were parallel. The brace bars will not interfere with ready spreading or contraction of the structure to lit the varying size or poles, or other supports. Other changes and modifications may also be possible which would still. come within the scope of the invention and I do -not therefore desire toibe limited to precisely what I have shown and described.

I claim the following:

1. In a secondary rack, the combination of a plurality of jib frames, Supporting bars to which the inner ends of the frames are secured, an insulator retainingrod carried by the outer ends of the frames, and a brace secured to the various frames to hold them rigid with respect to their supporting bars.

2. In a secondary rack, the combination of a plurality of parallel V-shaped jib frames, supporting bars connecting together the ends of the jib frames and adapted to be secured to a support, an insulator retaining rod detachably received by the outer ends of the frames, and diagonally extending brace bars secured to the limbs of the V-frames to lock said frames rigidly with reference to their supporting bars.
